"3 Claims. '1

This invention relates to improvements in the art of folding cardboardor other equivalent material, and more particularly to a means of curved scoring-and flexing to impart a threedimensional eifect to display devices, toys, and other objects constructed of foldable material. My prior U. S. Letters Patent No. 2,050,894, dated August 11, 1936. for folded blank boxes, sets forth a means of compensated scoring for the construction of cardboard boxes in which scores similar to those shown here are made to flex by making them in pairs, in opposed relationship constituting a tubular form. In this form, the scores act one upon the other to hold each other in flexed positiontherebysgiving form to the box and to themselves. 'As distinguished from my aforesaid prior patent, this invention embodies the feature of curved scoring of a flat blank of cardboard to divide the same into two or more panels in angular relation to each other, one always being convex and the other concave. In this invention it becomes necessary to provide additional means of holding the rest of the blank in bowed position in order to cause said curved scores to assume their flexed position. With the addition of art work thereupon, unusual depth is given to such devices, allowing them to appear as actual glasses, cans, tires, or other appropriate devices. The appearance of the curved score does not present a concave form to the eye of the observer. It looks like the. flat top surface of the drinking glass, can, tire. or other ob ect. It is this optical illusion which const tutes the greater part of the novelty of this invention. However, in certain forms, the curved surfaces are used decoratively, without thought to optical illusion.

Another feature of the invention resides in the art of curve scoring and folding cardboard in a novel manner to present an optical illusion of bulk and depth not present in the actual object display. While the invention is not limited in its display use, such items as canned food products, soft drink beverages in glasses, and other merchandise may be made the subject matter of display devices constructed in accordance with my invention, and when sodisplayed, the items stand out with startling realism due to the three-dimensional effect present therein.

Another feature of the invention is the provision of a simple and inexpensive means of forming three-dimensional objects such as dis= play devices, toys, plaques calendars, and other objects from flat cardboard by curve scoring and *folding to place the cardboard under bowed tension, there being means associated with the device tomaintain the same in set position under tension.

While I haveset forth above certain-of the featuresof my invention, othernovel features thereof will become apparent as the following specification is read in conjunction with the accompanying drawings, in which,

Referring to the drawings by reference characters and at present to the embodimentof the invention illustrated in Figures 1 to 7 inclusive, the numeral H3 designatesadisplaydevioe in its entirety which is of a shape resembling a drinkingglass.

The display device 10 includes an elongated body II constructed of a single blank of cardboard or other equivalent material capable of being cut, scored, and flexed under tension for reasons to be hereinafter appreciated. Normally the body iI is flat as shown in Figure and is die cut to provide a base I2 havin a straight bottom edge I3. The body II is provided with upwardly diverging side scores I l-l4 along which rearwardly and inwardly folded side flaps iii-I5 are integrally connected. The top edge I6 of the body is convexly curved and the flaps i5i5 extend from adjacent the ends of the top edge to a point adjacent the base I2 for reenforcing and tensioning purposes to be hereinafter explained.

The upper end of the body II is crease-scored on the curved line H which is struck from an arc greater than the are from which the edge I6 is struck and which extends in a reverse direction so as to be elliptically complementary to p the curved edge it. The ends of the crease-score ii are respectively connected to the curved edge It by curved end edges Iii-I8 to complete the ellipse. It will be noted that the curved creasescore' I? extends across the cardboard body from one edge to the opposite edge thereof and divides the body ll into a relatively long lower panel I9 and a smaller upper panel 20.

From the description thus far, it will be understood that if the panels I9 and 2B are folded relative to each other on the curved score I'I they will assume positions in angular relation under tension and will cause the panel I9 disposed on the convex side of the score IT to bow or flex forwardly while the panel 29 disposed on the concave side of the said score will bow or flex rearwardly or in a direction opposite to that of the panel I9. The direction of the outward bow of the panel I9 extends from the opposite side edges or fold scores I l-I4 while the inward bow of the panel'zt extends from one end of curved edge I8 to the other. The panels I9 and are now in the position as shown in Figures 1 to 4 and 6, but due to the tension which is now presen by the reversely bowed panels I9 and 20, some Integral with the flap 22 and connected thereto along a hinge score 23 is a prop flap 24. Integrally connected to the upper end of the prop flap 24 along a, hinge score 25 is a folding web 26 to which an attaching glue flap 21 is integrally connected along a diagonal hinge score 28. The glue flap 2i is glued to the rear side of the panel 20 as best illustrated in Figure 3. The easel 2l forms an operative connection between the folded reversely bowed panels I9 and 20 and also acts to reenforce the same.

The easel 2! is locked in set up position by the engagement of the'free longitudinal edge of the prop flap 24 with the vertical crease-score 29 provided on a cardboard bridge web 30 which has its ends glued respectively to the inner surfaces of the side flaps I5I 5. When the display device I0 is in fiat or collapsed position as shown in Figure '7, the bridge web is substantially fiat but when the device is in set up position, the prop flap 24 wedgingly engages the mid portion of the web, causing the same to assume a V-shape as seen in Figure 6, during which time an inward pull is exerted along the side edges of the body to maintain the reversely bowed panels l9 and to in folded position under tension. Also, the wedgingiy engaging easel and web serve to impart an outward bow to the panel i9 throughout its entire length, otherwise the panel l9 would only bow adjacent the curve score I! and gradually flatten out toward the base I2, due to the elongated nature of the panel I9.

The display device In is shipped or delivered to its place of display in a flat collapsed position as indicated in Figures 5 and 7. It will be understood that the front surface of the body II will have art work printed thereon to impart a more realistic effect. The body II simulating a drinking glass may be provided with art work simulating a glass containing a beverage and bearing the trade-mark and other advertising indicia appropriate to the advertised beverage. To set up the device Ill from its fiat collapsed position, the operator folds the body II on the curved score ll, causing the panel 20 to bow rearwardly and the panel I9 to bow forwardly in angular relation to each other, the direction of the reverse bows being at right angle to each other. Next, the prop flap 24 is swung to a, position at right angle to the glue flap 22 into wedging engagement with the bridge web 30, thus exerting a pull upon the opposed side edges of the panel E9 to maintain the tension upon the reversely bowed panels l9 and 20. The folding web 28 and glue flap 2'! act to exert a downward pull upon the concave panel 20 when the prop flap is in tight frictional engagement with the bridge web 33. The base I2 and prop flap 24 serve to support the display device in an upright rearwardly inclined position as shown in Figure 2. When the set up display device is viewed from the front, a third dimension is imparted, due to the forwardly bowed panel I9 and the rearwardly receding concave front surface of the panel 20. The impression obtained by ones sight is that of looking downwardly in perspective upon a glass containing a beverage. To collapse the display device It, it is only necessary to swing the prop flap 24 to a position flat against the attaching flap 22, thus relieving the tension upon the bowed panels I9 and 20, whereupon they will unfold to flat position due to their inherent tendency. I wish to point out that it is the curved score I! which causes the panels I9 and 20 divided thereby to bow or flex under tension in opposite directions. The easel construction acts to maintain the tension upon the flexed panels and to support the display device in a set up position for use.

In Figures 8 to 11 inclusive I have illustrated my invention embodied in a single disk-like display device 30, which in reality is the same construction shown in Figures 1 to '7, except that the body 3| is turned to a position at right angle to the body II, and is relatively narrow instead of elongated. The body 3| is constructed of a single blank of cardboard having convexly curved end edges 32 and 33, and straight top and bottom edges 34 and 35 respectively. The body 3I is provided with a curved crease score 36 which extends from the top edge 34 to the bottom edge 35 and which is connected to the curved edge 33 by top and bottom curved edges 31. The curved edges 33, 3'l31 and curved score 36 cooperate to provide an elliptical concave panel 38. The portion of the body 3I on the convex side of the cu ved score StconstitutBs a converte -rel 39. Whe th pan ls 38 and 39 are folded al ng the curved score 35. to. a position in angular relation. he. p nel :38 assumes .a concave or inwardly bowed position while the panel .39 zbows outwardly to. a convex position. Both panels are now reversely bowed under tension and for maintaining such tension I provide an easel 40.

The easel 40 includes a cardboard bridge piece 4| having its ends 4242 folded inwardly and glued to the rear surface of the outwardly bowed panel 39 adjacent the upper and lower ends thereof. Integral with the bridgepiece M and connected thereto along a hinge score 43 is a prop member 44. Integral with the prop member and cut from the bridge piece M is a presser tab 45 which tightly bears against the-rear face' of the convexly bowed panelBB when the easel is set up as shown in Figure l1=-to maintain the panel 39 and consequently the panel 38 in reverse bowed positions under tension. The bottom edge of the prop member 44 rests upon a flat supporting surface to support the display device 30 in set up display position. A display device of the design shown in Figures 8 to 11 inclusive may contain art work indicative of a tablet, disk, tire, or other circular object and when viewed from the front, imparts a third dimension to the eye of the observer.

In Figure 12 I have illustrated the principle of my invention embodied in a double disk-like display device 50. The device 50 is constructed from a single blank of cardboard in which the body 5| is provided with reversely convexly curved end edges 52 and 53, and opposed straight top and bottom edges 54 and 55. The body 5| is provided with suitably spaced reverse curved scores 56 and 51 which are complementary to and oppositely curved with respect to the respective convexly curved end edges 53. The curved scores 56 and 51 extend from the top edge 54 to the bottom edge 55 and are joined with the adjacent end edges 52 and 53 respectively by rounded edge portions 58. The curved scores 56 and 51 divide the body 5| into a pair of elliptical end panels 59 and 60 and an intermediate panel Bl. When the body 51 is folded on the double curved scores 55 and 51, the intermediate panel 6| bows forwardly from the top edge 54 to the bottom edge 55 while the elliptical end panels 59 and B0 bow inwardly. Suitable easel means such as shown at 40 in Figures 8 to 11 may be employed for securing the panels 59, BB, and El in bowed positions under tension, and will also serve to support the device 50 in an upstanding display position. The double disk display shown in Figure 12 may contain art work suggestive of a pair of candy disks, tires, or other circular objects.

In Figures 13 to 18 inclusive I have embodied my principle of curve scoring in a plaque-like display device 10, the same being formed from a single blank of cardboard as illustrated in Figure 13. The blank is scored horizontally on the parallel fold scores H and 12 to divide the same into top and bottom rear flaps '13 and 14 respectively and an intermediate body 15. The opposed side edges 'l6'l6 of the body 15 are of scroll shape. The body 15 is provided with reversely curved scores 11-11 which, extend from the ends of the score H to the ends of score I2. The reversely curved scores IL-1'! are in suitably spaced relation to the edges 16--l6 and divide the body 15 into end panels 18--18 and an intermediate panel 19. Integral with the mid portion of the end panels 18-18 and connected thereto alon whinse scores: tit-=80 are loc n tongues .8178!- $.l0ts 82-42. extend inwardly from the respective opposed edges cf-the tqn ues.

To set up the display device {Hi from the ,flat blank. .thez pera or fol s the body 50 1 the re ygrse curve scores ll-11 causing the int rmedi' atewpanel 9, to bow forwardly and. the end panels #18 extend rearwardly at an angle'to the panel 15 and tobow inwardly from one end to the other. The top and bottomflaps 13. and 74 are folded rearwardly and inwardly.- With their adjacent free end edges in spaced relation. To impart anwinward pull upon the convexly bowed .endpanels lit-48, the tongues 8l-Bi are folded rearwardly on the hinge scores 8l8ll into overlapping position and the slots ill-82 thereof brought into interlocking engagement- The slots .5-82 are so positioned upon the tongues that they ean onlybe brought into interlocking engagernent when the. panels l9 and.18|8 are folded under tension on the double curved scores ll- I! as best illustrated in Figure 16. When in folded and locked position, the display device 10 when viewed from the front appears as in Figure 14 and when appropriate art work is applied, the same imparts the appearance of a scroll having three dimensions. A hole 83 may be provided in the top flap 13 to facilitate the hanging of the set up device upon a nail or hook. The free ends of the top and bottom flaps underlie the locked tongues 8l8l which prevent them from accidentally unfolding.

While I have set forth herein several designs of display devices embodying the features of my invention, I wish it to be understood that such changes in design, material, and construction as some within the scope of the appended claims may be resorted to if desired without departing from the spirit of my invention.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:
